N2 - This paper proposed an architecture of an SRR transceiver for the applications in multi-target automotive environment. The millimeter-wave radar signal is phase-modulated by a specified Gold code sequence to make the reflection signal be capable of identification via auto-correlation. A 24-GHz PSK transmitter for the SRR application is also implemented. The original VCO frequency is designed at 12 GHz to release the constrictions of the CMOS process. Differential switches are employed in the transmitter for the purposes of the frequency doubling and the phase modulation. The PSK transmitter of the SRR transceiver is demonstrated in TSMC 0.13-um CMOS process. The chip size is 1.03 x 0.93 mm2. The measurement results show that the free-running frequency of the VCO in the chip is around 10 GHz and the doubled frequency is around 20 GHz. The phase modulator is also tested under a baseband frequency of 1 GHz and the result shows that it is functional work.
